A method of model reduction preserving design specification parameters for a class of dynamic systems

This paper is concerned with a method of model reduction for a class of linear controllable systems containing parameters with design specifications in their input terms. First, the structure of original model is shown, and a model retaining the parameters with design specifications is proposed as a reduced model. Secondly, on what condition the proposed model serves as a reduced model for the original model in similar sense of the dominant pole approach is investigated. Furthermore, the steady-state of reduced model is considered. Finally, a numerical example is demonstrated.<>
